| Research Abstract |
The subject of this research project was the Japanese gong, which is used in Kabuki performances, and its impressive, mysterious timbre. The relationship between the metalsmithing techniques used in hammering the gong's form and the quality of the sound produced by various prototypes was investigated at depth in collaboration with music psychologists, establishing a fruitful academic partnership between the faculties of Art and Music.
1.Gong prototypes were developed focussing on variations in form, size, and the metal thickness of each gong section, and how these changes affected the quality of the sound produced. Tests were conducted and data collated. It was established that gongs with semi-spherical centers had a better tonal balance, with a smoother flow of sound-waves from the center to the circumference, and more vibrations. Moreover, increasing the height of the gong's rim enhanced the sound quality even further.
2.Additional field-work research was conducted into the gongs of Bali, Korea and Laos, concentrating on the alloys used in their fabrication and how they influenced the quality of the sound produced by each instrument.
3.The gong prototypes which were made were tested in a sound studio using computers. After the timbre qualities were measured and analyzed, it was found that sounds with results peaking near 2kHz were richest in harmonic overtones and were the most aesthetically pleasing. In another experiment, people were asked to listen to the sounds produced by the gong prototypes. It became apparent from this survey that instruments which produced calm, powerful and beautiful sounds were rated the highest by the listeners.
4.Through further collaboration between Art and Music experts, it is the purpose of this research project to continue to examine in detail the relationship between the fabrication and sound quality of the gong, with the aim of improving the tone and expanding the versatility of this musical instrument.
